his invention relates to certain improvements in lifting-pumps, andconsists in the peculiar means employed for allowing, when necessary,the waste or surplus water to escape from the cylinder.

yTo enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A, represents the pump cylinder which may be constructed of cast metaland of suitable dimensions. On the upper end of this cylinder, a bowl ordish-sha ed fianch B is screwed, one side of which as a spout C. TheHauch Bis also constructed of cast metal. On the upper end of thecylinder A, an lu right pro'ection (a) is formed, through t e upper enof which the fulcrum pin (b1) of the handle D passes. The projection (a)is cast with the cylinder A.

The lower end of the cylinder A, is secured by bolts (b) (b) to a hollowbase E, which is also constructed of cast metal. At the center ofthe topof the base E, a screw (c) is secured, and the top of the base, aroundthe screw (c), is perforated with holes (d), as seen in Fig. 1, and alsoin dotted lines in Fig.

2. These holes (d) are covered by a circular iece of leather (e), whichhas a projecting ap (f) at one art of it. This flap (f) has two holes(1) (2li made through it, and a pin (3), attached to the top of thebase, is fitted in either of these holes, When the pin (3) is fitted inhole (l) a passage (4) is exposed, said passa eY leading into thesuction flanch or socket g); and when the pin (3) is fitted in the hole(2) the orifice of said passage (4) is closed. This will beunderstood'by referring to Fig. 2, in which the flap (f), as shown inblack, covers the orifice of passage (4), but exposes it when in theposition as shown in re On the upper surface of the leather (e), anannular chamber (h) is placed, the screw (c) passing through the center.The inner and outer edges of this chamber rest or bear snugly on theleather (e), as shown clearly in Fig. 1. This chamber (7L) has aprojecting flanch (i) formed" on it, said fianch being also providedwith two holes through either of which the pin (3) asses.

On the screw c) a circular plate (j) is screwed. This plate isperforated with holes (7c) and its outer part is curved, correspondingto the form of the upper surface of the chamber (h) see Fig. 1. n

The flanch or socket (g), at the under side of the top plate of the'baseE, is cast with the base. This flanch or socket (g) is of conical formas shown clearly in Fig. 1. And the upper end of the suction or eductionpipe F is fitted over the flanch or socket (g), the orifice of pipe Fbeing made of Haring or bellshape to correspond with the form of theianch or socket. The pipe F is as usual constructed of lead, and a brassor iron tube G is fitted over the upper end of the lead pipe F; theupper end of the tube G being made of bell-form 4corresponding to theupper end of pipe F.

H, represents acast metal bar having a conical o ening made through itto allow the pipe and tube G to pass through. And through the ends ofthe bar I-I, the bolts (b) (b) pass; said bolts have each two nuts (l)(m) on them; the nuts (l) secure the cylinder A to the base E, and thenuts (m), when screwed u tightly against the under side of the bar causethe conical opening in said bar to bind the upper end of the ipe Fsnugly around the socket (g). The base E is secured by screws to a proer platform I.

J, represents the piston w ich is secured to the rod K, the upper end ofwhich rod is attached to the handle D. The piston is formed of two parts(n) (o), both of which are constructed of metal, and the part (n) is acircular plate of slightly concave 0r dish form and perforated withholes (p) near its edge or periphery, as shown in Figs. 1 and 4. Theedge of the plate (n) is bent upward, as shown in Fig. 1. The other part(o) of the piston is formed of a ring connected by arms (1') to acircular plate s), through the i l NN Mw center of which the piston rodK passes. The lower end of the piston rod has a screwthread formed onit, and the plate or part (n) -is screwed thereon. L, re resents anannular piece of leather, iitted etween the outer part of the late (n)and the ring (o), and iirmly secure between them by screwing up theplate (n) suificiently on the lower end of the rod yK. The outer part ofthe leather ring L is bent upward and forms the packing of the pistonfThe inner end of the leather extends beyondand consequently covers theholes (p)1in the plate (n) .and forms the valve ol the piston.

The operationol' the pump-that is, the lifting andv discharging o' thewater-revquires no description, as it is precisely the same as that ofall simple lifting-pumps.

By adjusting the leatherA (e) so thaty the` passage (4) is exposed, thewasteorsurplus water is allowed to escape from the cylinder' A, into thesuction pipe F, and the pump cannot be frozen up Aduring the winter. Insummer, the leather isv so adjusted as to4 cover the passage (4) so thatthe packing of the valve may not shrink. The chamber (7L) serves as aprotection to the leather (e) and prevents the edges of the leather frombeing forced through the holes (d) by atmospheric pressure above as thewater descends in pipe F and produces a vacuum therein. The chamber (h)effectually prevents this.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is-

The leather (e) placed over the perforations (d) in the top of the baseE, and the chamber (h) which is placed on the leather; said leatherbeing provided witha flanch(f) provided with holes (l) (2), either ofwhich is fitted on the pin (3), for the purpose of exposing or closingthe passage (4), substantially asdescribed for the purpose specified.

BIRDSILL HOLLY.
